ELECTRICAL. GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent 110,352,473, dated November 9, 1886.

Application lileil January .16, 1886. Serial No. 159,774. (No model.)

T0 at whom it may concern:

Be it known that I, ADAM LUNGEN, a citizen of the United States, and a resident ofNew York, in the county of New York and State of New York, have invented certain new and useful Improvements in Electrical Gas-Lighters,of which the following is a specification.

Myinvention relates toan improved electric gas-lighter, and is adapted for use more especially with that class of gas-burners known as candle-burners, in which a' cylinder of porcelain or similar material is made to sun round the delivery-tube of the burner, to give the general appearance of a candle.

My invention belongsto that class of lighters wherein two electrodes-the one fixed and the other movableare connected with an electric battery in such a position relatively to the gas-burner as that the spark produced on breaking the electric circuit at the electrodes will ignite the gas as it rises from the burner. In the ordinary form of electric gas-lighter the movable electrode is of such a size and so shaped that it would be impossible to conceal it within the porcelain tube. Special lighters have been made for this class of burners, but have been found defective, for the reason that the small space within which they must neces sarily work limits the movement of the movable electrode and increases the liability of the electric circuit being permanently closed by a disarrangement of the parts.

My improvement consists in mounting the movable electrode so as to have a movement parallel with the axis of the burner, making the said electrode terminate in a spring arm, and in addinga guide-arm to control the movement of the movable electrode.

Myinvention further consistsin an improved form of the fixed electrode, by which a good contact is insured.

In the accompanying drawings, Figure 1 is ing the movement of the movable electrode,

and Fig. 3 is a top view of the device as shown A is the burner proper, and Bis a cylinder, of porcelain, glass, or similar material, surrounding the burner, and steadied in place by the annular disks to a,placed at intervals along the burner. i

O is a metallic electrode secured to the burner A near its upper end and insulated therefrom. lhis electrode 0 is made toextend along the burner to near its upper end, then bent to extend partly around the tip of the burner and made to terminate in a flat plate, 0, presenting its edge toward the burner, and lying in a plane cutting the axis of the burner and projecting above the burner, so that its upper edge will be near to the gas as it issues from the orifice in the burner.

D is a rod lying parallel to the burner A and within the cylinder B, and passing loosely through openings cut in the disks a a. Upon this red is a fixed stop or disk, (I, which. by bearing upon the under side of the upper disk 01, will limit the upward movement of the rod D. Around the rod D, and between the stop dand thelower fixed disk at is placed a spiral spring, E, which by its expansion will hold the rod D in its uppermost position. The rod D is made to terminate some distance below the top of the burner in a vertical line before the plate 0 of the fixed electrode 0, and to its up per end is attached a metallic spring-arm, F, to act as the movable electrode. The arm F is made to extend first upward from the rod D for a short distance, and in this space may be bent around in a spiral form to add to its resiliency, then diagonally across in a plane tangent to the side of the burner A, then upward, and at its upper end is bent inward toward the burner to form a tip, which,when swung backward and forward, will move in the same tangent plane with reference to the burner as the plate 0 on the fixed electrode.

A guide spring, H, is secured to that side of the burner opposite the fixed electrode within the cylinder B,and, extending upwardly alongside the'burner, is bent inwardly and made to rest against the diagonal portion of the springarrn F of the movable electrode. The guidespring H is made strong enough to overcome the resiliency of the spring-arm F, and the two are so proportioned that when the rod D is in its uppermost position the tipf of the arm F will stand ofi' near one side of the cylinder B, and the guide-spring H will bear upon the said arm at the lower end of the diagonal part thereof. A downward pull upon the rod D will compress the spring E and will cause the diagonal part of the arm F F to slide over the end of the guide-spring till the tip fis forced over against the plate 0 of the electrode 0. A continued downward movement will cause the tip fto slide along the plate 0, and the spring H will be bent outward till the tip f passes the lower edge of the plate 0, when the spring H will force the arm F over till its tipf is in position to be moved up by an upward movement ot the rod D on the opposite side of the plate 0. As soon as this upward movement of the rod begins, and by reason of the inclined or diagonal part of the same sliding over the end of the guide-spring H, the re siliency ofthe arm F will press its tip fagainst the plate 0, upon which it will slide till it reaches its upper edge, where it will snap off and return to its original position. The several positions ofthe arm F and the guide-spring H are shown in Fig. 2. The downward move ment of the rod D to operate the arm F is accomplished by means of a cord or rod, 1, attached to its lower end, extending downward to a point below the burner, and provided with a knob or handle, 2'.

It will be understood that the fixed electrode 0 is connected with an electrical generator. The movable electrodes D F, being in contact with the gas-pipe, will complete the circuit to the ground during its movement.

What I claim as my invention is- In an electric gas-lighter, the combination, with a gas-burner and with a fixed electrode attached thereto and insulated therefrom, and a sliding sp ring-actuated rod carrying a springarm to act as an electrode to make and break the electric circuit, of an auxiliary guide to govern the movement of the movable electrode, substantially as and for the purpose set forth.

Signed at New York, in the county of New York and State of New York, this31st day of October, A. D. 1885.

ADAM LUNGEN.
